Given that you are sending channelized data from the 2600, you will need an external CSU for the 2500 to return the channelized data from the 2600 back to serialized data. The cabling between the two CSU's is a simple crossover cable where the pinout is:
1 -- 4 2 -- 5 4 -- 1 5 -- 2 Then you'd need a V.35 to (presumably) DB-60 for the connection from the CSU to the 2500. Configure the CSU's to utilize all 24 channels, and POOF...Simulated T-1... Hope this helps.

I have a Cisco 2600 with a T1 csu/dsu and 2 Ethernet connections I want to simulate a wan environment with a 2500 with 2 serial connections and 1 aui Ethernet. What type of cabling do I need to establish a connection between the 2 routers? If the T1 csu/dsu takes rj48 ? how do I connect that to the serial connection on the 2500? DTE/DCE v.35 Will I need a CSU/DSU ?
